MEANS OR APPARATUS FOR OBTAINING lVlOTlVE owaa.

SPE GIFICATIQN forming part of Letters Patent No. 274,256, dated March 20, 1883. Application filed April 1, 1882. (No model.)

To all whom it may concern Beitknotwn thatI, J osEPH EDWARD BARRY, a citizen of the United States, of the city, county, and State of NewYork,have invented certain new and useful Improvementsin Means or Apparatus for Obtaining Motive Power, of which the following is a specification.

My invention 1 relates to improvements in that description of apparatus for obtaining motive power in which the said power is derived from floats which are caused to rise and fall according to the rise and fall of the level of the water in which they are floated.

My invention consists in the employment of two classes of floats confined in chambers or dams, one classoffloats being arranged in chambers or dams the water-way or sluice to which is constantly open to the action of the tide or water supply, and a second class of floats which are also arranged in chambers or dams separate from the chambers or dams of the floats of the first class, the water-way or sluice of the chambers or dams of this second class of floats being controlled by doors or gates, which are only opened for the passage of water and closed against such passage at intervals, such intervals being controlled by the action of the floats of the first class, and so timed that the floats of the second class shall not commence to rise until the floatsof the first class have obtained a considerable portion of their entire rise, the object of thus delaying the action of the floats of the second class being to prevent the stoppage of the apparatus during the,

turn of the tide or the change of direction of the flow of the water-supply to the dams or chambers.

In carrying out my invention I arrange a line one with the other, each in a separate dam or chamber. Each float is provided with a pair of vertical standards, firmly bolted or connected thereto, and passing up through a permanent platform in which the driving mechanism is supported, as hereinafter explained. Each of these standards has formed on or affixed to one of its faces a rack or series of teeth arranged to gear with one of a pair of cog-wheels, each of which is mounted or formedon a sleeve capable of turning freely on a horizontal drivingshaft.

on opposite sides of a disk or wheel firmly fixed upon the driving-shaft, and provided on its opposite sides with a right-antlJeft-handed spring-pawl, or its equivalent, adapted to en gage with a correspondingly-ibrmed ratchetwheel or its equivalent engaging mechanism, so arranged that when the float is rising one mechanism shall come into operation and the other remain idle, and when the float is falling the opposite one shall come into action and that which had been at work shall remain idle, thereby insuring that the shaft shall always be driven in one and the same direction. The horizontal driving-shaft is formed in sections connected together by coupling plates or disks affixed to the ends of each section, and through which pins or studs are passed. Motion is communicated from the main shaft to a train of gear-wheels mounted on shafts working in bearings carried by, a substantial framing. On the last or such other shaft as may be most convenient or desirable, or on one or moreofsuch shafts,is mountedadriving-pulley or driving-pulleys, from which motion is com;

municated to other driving-shafts for the purpose of operating machinery.

A Any. number of floats and their connected mechanism may be employed in conjunction with a single driving-shaft, and the said shaft may communicate motion to'a single train of geared wheels, or a series of trains of' geared wheels may be employed. The object of the gearingand trains of wheels is (as will be manifest to any one acquainted with mechanics) to convert the slow vertical motion of the floats into a sufficiently rapid revolving motion adapted for operating machinery or for other purposes. One or more of the series of floats I arrange in a dam or chamber, the sluice of which is controlled by mechanism controlled by the main floats, which is brought into operation for the purpose of opening the sluice of the dam of the auxiliary floats at any desired time, but by preference shortly before the turn of the tide or the filling of the main dams or chambers, the object of this auxiliary dam beingtoinsure the regular rotation of the main or driving shaft during the turn. of the tide, or the time which must necessarily be ing the sluices.

consumed while the water in the main tanks is ceasing to rise and commencing to fall. The admission of water to the reserve tanks must be gaged to equal the speed at which the water was or is being admitted to the main tanks, in order that there shall not be any variation in the speed of the machinery. The machinery can be stopped at any time by clos- The area of the reserve floats must equal that of the main floats, and the weight of the floats should always equal their upward pressure.

The accompanying drawings form part of thisspecification, and illustrate what I consider the best means of carrying out the invention.

-Figure 1 is a plan viewof the apparatus. Fig. 2 is a section of the same on the line x of Fig. 1; Fig. 3 is a section on the line y y of Fig. 1. Fig. 4 is a side elevation,partly in in section, on a large scale, showing one set of the gearing andthe driving mechanism. Figs. 5 and 6 are detached views.

- .In each of the views similar letters of reference indicate corresponding parts wherever they occur.

A and A represent a pair of floats, of which there may be any number of duplicates in the series. A isthe main float, and A the auxiliary or reserve float. Each of these floats A and A is arranged in a separate tank or reservoir,

, Z Z, provided with sluices z z, and each float has mounted on it a pair of vertical standards, B and B, which are firmly bolted thereto and pass up through the permanent platform 0, which may be supported on spiles or other suitable foundations over the water-way or the tanks or receivers'in connection with the said water-way or source of water-supply. Each of these standards B B has formed on or affixed to one of its faces a rack or series of teeth, 1), arranged to gear with one of a pair of cog-wheels, D I), each of which is mounted on a sleeve, cl or d, capable of turning freely on a horizontal driving-shaft, E, supported in hearings in the framing flrmly bolted to the platform 0. The mechanism of the floats A is arranged to act alternately with the mechanism of the floats A.

In the drawings, Figs. 1 and 2, I have shown the cog-wheels D and D arranged on opposite sides of a pair of disks or wheels, F F, both of which are firmly fixed upon the driving-shaft E, and provided on one of their opposite sides with a right-handed spring-pawl, f, adapted. to engage with the teeth 9 of a ratchet-wheel, G, mounted on the sleeve (1, while on the other side the disks or wheels F F are provided with left-handed pawlsf, adapted to engage with the teeth 1 of ratchet-wheels Gr, affixed on the sleeves d. The mechanism is so arranged that when the floats A or A are rising the racks b of the standards B will. drive the shaft E by reason of the pawls f falling into one of the notches g of the wheels G and driving the shaft E, while when the floats A or A are falling the racks b of the standards B will drive the shaft E by reason of the pawls f falling into one of the notches g of the wheels G, and thereby continuing the motion of the shaft E in the same direction. It will thus be seen that the shaft E will be driven in the same direction at all times irrespective of the rise and fall of the floats A and A.

The horizontal shaft E is shown formed in sections E E Eiwhich are connected together by means of coupling plates or disks 6 e, the said plates being bored with holes adapted to receive pins or studs 6 which pass through the same and form a secure connection. Other forms of coupling may, however, be employed.

L is a standard affixed to the main float A, for the purpose of drawing upon a cord or chain, 1, connected to the door or gate 2 ot' the sluice z, of the dam Z, This cord or chain is conducted between adjustable bearing-rollers m, carried in sliding bearings m, mounted in a frame, M, and also over a stationary pulley, n, carried by a standard, N, supported by the platform 0. The sliding bearings are held in position centrally when the float A is in a state of inaction, with its sluice 2 closed and its tank Zempty, by means ofa pair of springs, O, which are of suiflcient strength to bear the ordinary draft on the rope or chain 1; but when any undue strain is broughton the said rope or chain, owing to an excessively high tide or an excessively low tide, they will give way and allow of the vertical displacement of either of the pulleys m.

The mechanism for operating the sluice z of the dam Z is by preference timed to act shortly before theturn of the tide.

Motion is communicated from the main shaft E by means of teeth formed on the periphery of the wheel or disk E, which engage with the teeth of a pinion, H, mounted on a shaft, h, revolving in bearings carried by the framing c. On the shaft is also mounted a cog-wheel, H, which engages with the teeth of a pinion, I, mounted on a shaft, '5, revolving in bearings also carried by the framing c. On the shaft 6, I also mount a cogwheel, I, which engages with the teeth of a pinion, J, amxed on a shaft, j, on which are also mounted the fast and loose pulleys K K, by the former, K, of which motion may be communicated by means of a drivin g-belt to other driving-shafts for the purpose of operating machinery or for other purposes.

In place of the driving-pulley, I can employ a crank, eccentric, or other means of imparting motion.

' K is a fly-wheel mounted 011 the shaftj for the purpose of equalizing the velocity of revolution of the mechanism.

I claim as my invention-=- 1.
